Diagnosis. The new species is distinguished from M. confracta sp. nov. by the spacing of the teeth of the stridulatory file, of which the basal teeth are gradually becoming smaller proximad ( Fig. 5h ).

Bioacoustics (see song parameters in Table 3). For its song type, a song unit is made up of several different-amplitude subunits. One subunit consists of 2 simple syllables. The neighboring subunits are broken ( Figs 2 f–i). This new species is widely distributed in southern China (including Yunnan, Guangxi, Guangdong, and Hainan).

Etymology. The species name indicates its song unit consists of a series of chirps.
